Evaluate following double integral value taking 4 segment for both x and y direction use Simpson rule ∫(2)_(4)∫(x)_(3x^2) ((3x^2)+y) dy dx
obtain second order derivative y'' using Taylor series Expansion using 4 point
solve the problem d^2T/dx^2 = dT/dt when
T(0,t)=200,T(1,t)=200,T(x,0)=0 using boundary and initial conditions above with dalta x =0.2 solve the parabolic equation for dalta t=0.04 and dalta t=0.015 time step. compare there two results.
A new design of nitrogen charged accumulator, for use in a hydraulic circuit, is being factory tested for certification purposes.(http://www.accumulators.co.uk/). The following data has been collected by a technician:
o Gas volume: V = 0.8 m3
o Gas pressure: p = 160 kPa
o Compression index: n = 1.4
o Pressure/volume relationship: pV ⁿ = C
o Work done =
i. Evaluate C.
ii. Calculate the work done in compressing the nitrogen from 0.8 m3 to 0.6 m3 using:
o integral calculus
